Solar system in an enclosed trailer

I am new to the DIY Solar system.
I have 18 ft enclosed trailer that I have insulated and put up 5/8 plywood.
I have renogy 1280 w of solar panels and using 4 renogy agm batteries to power the items in the trailer.

My question is, do i need to vent the batteries since it is an enclosed trailer?

If so what is the best way to vent the batteries?

Thanks in advance.

I have read what you attached but this still does not tell me if they batteries need to be vented in an enclosed trailer.

These are the batteries I am using.
Renogy Deep Cycle AGM Battery 4-Pack 12 Volt 100Ah, 3% Self-Discharge Rate, 2000A Max Discharge Current, Safe Charge Most Home Appliances for RV, Camping, Cabin, Marine and Off-Grid System

It depends on your level of paranoia. One of the advantages of AGM over a flooded battery is that it only off-gasses when you really cook the krap out of it and things go wrong. Under normal operation they don't release anything, and if you did get a little gas in the trailer it wouldn't affect anything. If you're cooking your batteries under really heavy charge loads, you might have an issue but just the process of opening the door to look is going to get the hydrogen out and below a flammable level. I wouldn't worry about it unless your controller freaks out or you're putting over 100a to the battery bank.

Is there a reason you didn't go with LFP? Lighter, longer lifespan, more usable watts per square inch of footprint, more usable watts per dollar. Or is cold a factor? If you need your batteries to work normally below freezing then AGM is the way to go.

Thank you for the information, this is my first go around with solar and a friend recomended the system.

This was a learning curve for him as well for the application i am using it for.

I will more than likley be upgrading as I start using it on a regular basis.
